my camera lens wont open

You tried to take out and putting back on the battery. But have you tried to check if the battery has still the power? I had a similar experience with you with my canon remote control camera. I thought it was already damage because I cannot open the shutter lens. So I brought it to the service center. The technician simply put a new set of battery and it worked. . I asked if how much would I pay for it, the man did not charge me anything. :-) From that time on, whenever I encounter a problem like the lens won't open, I just tried to change the battery and it worked. Now with my new nikon camera, i also encounter the same problem. I only change the battery and the problem is solved. So try to change your battery. Not simly taking it out and put it back again. Maybe it needs a new set of batteries. :-)

I watch vloggers who use their digital cameras all the time and sometimes the "eye" of the camera, AKA the lens will close. They take and tap it with their finger or pry it open and it works fine. Have you tried this? I'd try it, not to the point it'd break but atleast to see if it would open.
